Mystery Sylvania from my childhood

[TUD1]

I was reminded of a set that I knew many years ago in middle school, and I was wondering if anybody has any idea what set it could be. It was a late 70's, early 80's Sylvania with the newer Sylvania logo. As far as I can remember, it was a standard 19" knob tubed set with AFT on the front and a smoke grey plastic case with woodgrain. I would love to find the set to be able to finally have one. I'd love to see pictures to see if I could identify the set. I also remember that the mask did not "fold" to meet the CRT. It went directly from mask to CRT with no corner in the mask. Just like an 80's RCA.
